Title: Contacting and soldering method for integrated circuit
Inventor: SHIIINNEN CHIYANGU
IPC: B23K1/00
Filed: 1989-12-22
Abstract: PURPOSE: To make it possible to enhance wettability and to embody fusion bonding free of voids by executing low-temp. welding in a fluxless state in a reducing atmosphere by using a layer contg. Pd and having a specific thickness and the material selected from copper and solder in contact with this layer. CONSTITUTION: The material consisting of the first layer of a thickness about 200 to 1500 Å contg. the Pd and the second member selected from the copper and solder in contact with the first layer is formed. The Pd thin-film layer functions in the reducing atmosphere at the time of solder melting and enhances the low-temp. melting in the fluxless state. The Pd layer 1 has corrosion resistance when the layer 2 is a layer of copper as an intermediate product in a melting and bonding work step. When the melting work is, therefore, carried out in the reducing atmosphere, the Pd layer eventually makes up the insufficiency of the reduction power of the reducing atmosphere at the time of reducing the oxide existing in a melting region and the wettability of the copper at a low temp. may be fundamentally improved.  As a result, the wettability by the molten material is enhanced and the connection may be executed at the drastically lowered temp.

Title: Logical verification method
Inventor: HOSOMI SHUNSUKE
IPC: G06F11/26
Filed: 1989-12-20
Abstract: PURPOSE:To save a memory area used in logical verification and to accelerate the logical verification by handling wiring elements which comprise an electrical circuit and an electronic circuit as one active element, and permitting the wiring element to provide with the same delay value as that of the active element. CONSTITUTION:In a wiring delay input procedure, delay time is permitted to supply to the wiring to which delay is desired to supply, and at this time, the delay value is permitted to supply with the combination of the wiring element from terminal to terminal. For example, the delay time from a terminal 5 to a terminal 6, the delay time from the terminal 5 to a terminal 7, and the delay time from the terminal 5 to a terminal 8 are supplied. After that, a logical simulation program recognizes the wiring element to which the delay is supplied as the active element, and performs simulation, and displays a verification result. Thereby, it is possible to perform the logical verification handling the delay of the wiring element without changing a net list before inserting a delay element.

Title: Register system for assimilated sound
Inventor: TAKESHIMA KAZUO
IPC: G10L15/06
Filed: 1987-12-28
Abstract: PURPOSE:To efficiently register sound patterns of assimilated words by preliminarily extracting combinations of words, which are apt to be assimilated when being continuously spoken, from preliminarily limited words and reporting readings of these extracted words to a specific speaker to instruct him to speak them and segmenting assimilated words. CONSTITUTION:Based on the report that registration of words limited by the specific speaker is completed, a control part 4 instructs an assimilation discriminating part 5 to indicate speaking of a word string, which includes the combination of words which are preliminarily stored in this part 5 and are apt to be assimilated at the time of continuous speaking, to the specific speaker through a speaker 6. A sound collating part 2 DP-collates the sound pattern of the designated word string inputted through a voice input part 1 with sound patterns of words already registered in a dictionary 3. Thus, sound patterns of assimilated words are efficiently registered in the dictionary 3, and the recognition error due to his continuous speaking of words is prevented.

Title: Computer system
Inventor: HISHINUMA YUKINOBU
IPC: G06F12/16
Filed: 1987-12-28
Abstract: PURPOSE:To prevent the breakdown of the storage contents of a main memory when a system clear signal is produced by inhibiting the access actions of an internal device which performs the accesses to the main memory via a system bus and at the same time clearing the actions of said device. CONSTITUTION:When a system clear signal SCLR request switch 7 is turned on and the signal SCLR is produced, a system bus competition circuit 4A of a system clear controller 4 occupies a system bus 5 in preference to other system bus competition circuits 2A and 3A. When the occupation of the bus 5 is through with the circuit 4A, the clear signals are supplied to a CPU 2 and an I/O 3. Thus a computer system is cleared. Under such conditions, the bus 5 is controlled by the circuit 4A and therefore the CPU 2 and the I/O 3 are unable to have accesses to a main memory 1. Thus, the storage contents of the memory 1 are secured and therefore the breakage of memory can be avoided when the system is cleared.
